Abstract

In foggy conditions, acquired images have low contrast ratio and low scene visibility problems. The traditional defogging algorithm has high time complexity and low speed characteristics and can not be applied in real-time image processing. Thus, a single image restoration method based on mean filter is proposed in this paper combined with the optical properties of atmospheric. In this method, on the basis of atmospheric scattering model, accurate atmospheric dissipation function can be achieved firstly by using mean filter. Atmosphere light is obtained by quadtree algorithm which is more efficient. Finally, restored image is calculated by the atmospheric scattering model and the brightness of the image is adjusted, and a clear image without fog is gained. Simulation results show that this algorithm has a strong adaptability to various scenes and restored images have plentiful colors. Compared with the classic defogging algorithm, this algorithm ensures the defogging effect while overcomes the high time complexity and low speed defects of guide filter algorithm.
